    Was very happy with the big lever until the bolt snapped on the other side, would prefer a more universal bolting system that eventualy ,in case of a brake-down, can be replaced, other than that very functional,bought it cause of the cold condition here high up in Norway, a big lever is easy to find and to open with gloves and frozen fingers. Vivid colours to!
